LATCH-LIFTING MEMBER.

Specification of Letters Patent.

Patented Aug. 8, 1905.

Application filed March 20,1905. Serial No. 251,121.

To all whom, it may concern:

Be it known that I, WALTER H. HART, a citizen of the United States,residing at New Britain, county of Hartford, and State of Connecticut,have invented certain new and useful Improvements in Latch-LiftingMembers, of which the following is a full, clear, and exact description.

My invention relates to improvements in latches, and particularly to theconstruction of the latch-lifting member.

The main object of my invention is simplicity of construction andeconomy of production.

As ordinary thumb-latches are well known, it is unnecessary for me toillustrate herein anything except the particular member to which thisimprovement is confined.

In the accompanying drawings, Figure 1 is a perspective view of alatch-lifting member constructed to embody my invention. Fig. 2 is anend elevation thereof looking from left to right.

The article is made from a flat sheet of metal, and the transformationof the same into the finished article is brought about by the use ofsuitable dies, the particular construction of which is immaterial tothis invention In the drawings, A represents the shank of alatch-lifting member, which at one end terminates in the hooked portionB andat the other end in the flattened finger-piece C. The hookedmember, as well as the shank, is hollowed on its lower side by bendingdown the opposite edges of the metal so that the shank will assume aU-shaped cross-sectional outline. The thumb-piece C may be curved tocorrespond with the outline of the usual thumbpiece, and thisthumb-piece C is connected to the shank A by whatI term the crown D, theside walls E E of which crown diverge gradually from the parallel intosaid flattened thumbpiece, and thus strengthen and substantially supportthe flattened thumb-piece, giving to it great rigidity even though itmay be formed of comparatively thin metal.

From the foregoing description it will be seen that the latch-liftmember as a whole is very light, may be cheaply and quickly produced,and yet, because of its novel formation, will possess great strength andrigidity; In the drawings I have not attempted to illustrate theparticular form that the article would assume in its finished condition;but as to general outline the drawings furnish a sufficientillustration. Of course the open side of the channeled portion of theshank may be closed in, if desired, without departing from the spiritand scope of my invention.

What I claim is A latch-lift member comprising a shank, a

hook at one end thereof, said shank and book being hollowed, a flattenedthumb-piece at the other end of said shank, and an intermediate crownbetween said thumb-piece and shank, the sides of said crown graduallydiverging so as to merge the opposite side walls of the shank into theplane of said flattened thumb piece.
